Nuki 3.0 Pro Wi-Fi not found


the device does not see my Wi-Fi in the list of available networks but all the others nearby. Not even entering data manually. Obviously the Wi-Fi works regularly and is also divided by network 2.4/5, coverage is guaranteed at that point.

Wi-Fi: FRITZ!Box 3490
FRITZ!OS: 07.31
SSID not hidden, WPA2

Nuki 3.0 Pro
Firmware 3.7.7

Thanks in advance.
